This check valve is designed to allow maximum water flow from your pump. The clear valve body shows if water is moving and the pump works as designed. The spring-loaded flapper keeps the operation quiet, with no jarring water hammer noises. Our sump pump check valves are made with easy installation in mind and come with stainless steel clamps and Buna-N couplings that fit 1-1/2″ pipe. This sump pump check valve can quietly prevent water from being pumped twice and extend the life of a pump. Product Specs: Model: CV-150, 1 1/2 inch check valve, spring-loaded flapper Dimensions: 8.5 x 3 x 3 inches; Weight: 12.8 ounces. ## Features - QUIET OPERATION: Our sump pump check valve has a unique spring-loaded flapper that helps eliminate the water hammer noise that standard check valves produce. The water hammer noise occurs when the discharged water slams the check valve flapper down. This silent check valve can bring a quiet operation to your sump pump. - CLEAR VALVE BODY: This check valve will provide visibility to water movement. With the valve's clear body, it's easy to visually confirm that pumped contents are moving, the pipes are not clogged, and the pump in the basin is fully operational. - INCLUSIONS: Our silent sump pump check valve comes with stainless steel clamps and Buna-N rubber couplings for quick installation. The clamps and couplings fit a 1-1/2" Schedule 40 pipe. Fits within a 5-1/8" gap. - KEEP WATER OUT: This check valve is designed to keep pumped water within the discharge pipe from falling back into the sump basin. A fully functional sump pump check valve can increase pump life expectancy by preventing water from being pumped twice. - ABOUT US: PumpSpy provides sump pump systems that help eliminate the unknowns of a sump outage and prevents costly damage. We also offer Smart Sump Pump Systems that automatically track incoming data and check that a sump pump is working properly. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B091V15RHZ | | ASIN | B091V15RHZ | | Brand Name | PumpSpy | | Color | Clear | | Customer Reviews | 4.7 4.7 out of 5 stars (1,893) | | Customer reviews | 4.7 4.7 out of 5 stars (1,893) | | Date First Available | 12 April 2021 | | Global Trade Identification Number | 00850004841143 | | Item Dimensions L x W x H | 7.6L x 21.6W x 7.6H centimeters | | Item Weight | 0.8 Pounds | | Item model number | CV-150 | | Manufacturer | Raybend | | Manufacturer | Raybend | | Manufacturer Part Number | 93100-01 | | Material Type | ABS | | Model Number | CV-150 | | Power Source | Ac/dc | | Product Dimensions | 7.62 x 21.59 x 7.62 cm; 362.87 g | | Product Style | Submersible | ## Product Details - **Brand:** PumpSpy - **Colour:** Clear - **Material:** ABS - **Product dimensions:** 7.6L x 21.6W x 7.6H centimeters - **Style:** Submersible ## Images ![PumpSpy Silent Check Valve - 1-1/2" with Buna-N Couplings, Model CV-150, Spring-Loaded Flapper, Sump Pump Life Expectancy Increase, Includes Steel Clamps Fit 1-1/2″ Pipe - Image 1](https://m.media-amazon.com/images/I/71lB0cGelrL.jpg) ![PumpSpy Silent Check Valve - 1-1/2" with Buna-N Couplings, Model CV-150, Spring-Loaded Flapper, Sump Pump Life Expectancy Increase, Includes Steel Clamps Fit 1-1/2″ Pipe - Image 2](https://m.media-amazon.com/images/I/81iF8LZ-bAL.jpg) ![PumpSpy Silent Check Valve - 1-1/2" with Buna-N Couplings, Model CV-150, Spring-Loaded Flapper, Sump Pump Life Expectancy Increase, Includes Steel Clamps Fit 1-1/2″ Pipe - Image 3](https://m.media-amazon.com/images/I/81MmaHD0-aL.jpg) ![PumpSpy Silent Check Valve - 1-1/2" with Buna-N Couplings, Model CV-150, Spring-Loaded Flapper, Sump Pump Life Expectancy Increase, Includes Steel Clamps Fit 1-1/2″ Pipe - Image 4](https://m.media-amazon.com/images/I/81UUu27THlL.jpg) ![PumpSpy Silent Check Valve - 1-1/2" with Buna-N Couplings, Model CV-150, Spring-Loaded Flapper, Sump Pump Life Expectancy Increase, Includes Steel Clamps Fit 1-1/2″ Pipe - Image 5](https://m.media-amazon.com/images/I/81Mj9zOJJKL.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - PumpSpy Silent Check Valve - 1-1/2" with Buna-N Couplings, Model CV-150, Spring-Loaded Flapper, Sump Pump Life Expectancy Increase, Includes Steel Clamps Fit 1-1/2″ Pipe - PumpSpy Sump Pump Stand - Increases Sump Pump Life, Prevents Sediment Buildup and Clogging, Compatible with Most Pumps - Wayne 58321-WYN3 CDU980E 3/4 HP Submersible Cast Iron and Stainless Steel Sump Pump with Integrated Vertical Float Switch, Large, Silver --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ph/products/364632387-pumpspy-silent-check-valve-1-1-2-with-buna-n](https://www.desertcart.ph/products/364632387-pumpspy-silent-check-valve-1-1-2-with-buna-n) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-09-04*
